Shell small, whitish, turreted, with about six whorls, the nucleus de¬ 
fective, the suture distinct, not appressed; spiral sculpture of a strong keel 
at the shoulder and on the base four or five feeble threads, the canal with¬ 
out spiral sculpture; axial sculpture of (on the last whorl about 18) 
rounded riblets retractive behind the keel, protective in front of it, 
straight, forming a nodule at the intersection with the keel and with wider 
interspaces; aperture short and wide, simple, the anal sulcus coinciding 
with the end of the keel. Height, 11; diameter, 4 mm. (Dali.)

Plate 11, fig. 11 
Canadian Geological Survey, Memoranda, No. 1143, 10; Pi. 1, fig. 5. 
Shell small, fusiform, greenish-white, with about six whorls. First 
whorl of nucleus, flattish, minute, apparently smooth; second whorl with 
a sharp prominent shoulder-keel, crossed by numerous minute riblets, much 
lower than the keel. On the next whorl the periphery bears a keel like 
that at shoulder, and the riblets gradually become stronger, and fewer in 
number, diminishing, however, on the following whorls to mere axial 
striations; the peripheral keel also losing its prominence. On the later 
whorls, which still-preserve, though with less prominence, the keel at the 
shoulder, the spiral sculpture becomes predominant, and on the spire there 
are about four spiral threads between the shoulder and the suture in front 
of it and on the last whorl about ten between the shoulder and the begin¬ 
ning of the canal, which is also spirally striated. The prominent shoulder 
gives a turreted aspect to the whorls; the aperture being narrow; the outer 
lip sharp; the anal sulcus shallow and feeble; the pillar white, and at¬ 
tenuated in front; and the canal short and wide. The operculum ovate, 
somewhat concave with an apical nucleus. Height of shell, 8.5; of last 
whorl, 5.5; of aperture, 4 mm. (Dali.)
